FURROW-OPENER ATTACHMENT.

SPECIFICATION forming part 'of Letters Patent N 0. 732,191, dated June 30, 1903. Application filed November 25, 1902. Serial No. 132,717. (No model.)

To all whmn it may concern:

Be it known that I, CLAUDE S. KEMPER, a citizen of the United States, residing'at Cameron, in the county of Clinton and State of Missouri, have invented certain new and useful Improvements in Furrow-Opener Attachments; and I do herebydeclare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention, which relates to furrowopenerattachments,is animprovement on the construction of attachment for which Letters Patent No. 679,025 were issued to me July 23, 1901.

The objects and nature of the improvements will be readily understood, reference being had to the following detailed description and to the accompanying drawings, in which- Figure 1 is a perspective View of a furrowopener embodying the improvements attached to the shoe of a corn-planter. Fig; 2 is a plan view of the furrow-opener. Fig. 3 is an enlarged vertical sectional view of one of the disks and its axle. Fig. 4 is a sectional view through the axle-block and supporting-standard.

Referring to the drawings by numerals, 1 designates the shoe of a corn-plan ter to which my improved furrow-opener is adapted to be attached.

2 is the seed-tube at the heel of the shoe. The shoe and tubemay be of any construction, it being understood that one of the objects of the present invention is to provide an attachment which by reason of certain capabilities of adjustment render it adaptable to various types and sizes of planter-shoes.

Fixed to and extending laterally at an angle to a block 3 are axle-stubs 4 4, on which are mounted disks 5 5. Each disk hasa hub aportion of which, 6, extends outwardly from the concave face of the disk and beyond the end of the axle-stub 4, providing a chamber 7 for oil, which chamber is closed by an inserted plug k- The hub is intermediately flanged for attachment to the disk, and the opposite hub end 9 is provided with a flange 10. The hub is loose on the axle-stub and rotates thereon, and its position along the stub is fixed by means of a set-collar 11 and a screw 12. The collar 11 has an upwardlyextending arm 13, to which is attached the lower end of a scraper 14. A plate 15 is secured to one side of the arm 13, preferably by the bolts and nuts which fasten the scraper, and its lower end engages the flange 10 and maintains the adjustedposition of the disk, while permitting its rotation. Obviously by loosening the set-screws 12 the disks may be adjusted to or from each other, according to the width of the furrow desired.

The block 3 has a vertical opening receiving a preferably tubular standard 16, which is square in cross-section. The side walls of the opening in the block 3 are inclined, as shown in Fig. 4, and 17 17 are set-screws passed through the block and tightened against the standard, whereby to maintain the vertical adjustment of the disks, accord ing to the depth of furrow desired.

The lower end of the standard has a notch 18 engaging the upper edge of the shoe 1,and the upper end of the standard is supported by a bracket comprised of two bars 19 19, the rear ends of which flank and are clamped against the seed-tube by a bolt and nut 20 and the front ends of which flank the toe of the shoe and are secured to each other and against the toe by bolts and nuts'21 21. A plurality of bolt-holes 22 22 are provided for any desired adjustment and to permit of the attachment of the bracket to different sizes and makes of shoes. The rearward ends of the bars are separated to the proper extent to admit the seed-tube by ofisets 23 in the bars.

24 24 are blocks between which is confined the upper end of the standard, said blocks being clamped between the bars by bolts and nuts 25 25. Each block is provided with upper and lower flanges 26 26, between which the bars are confined.

I claim as my invention- 1. A furrow-opening attachment for planters and the like, comprising disks mounted to have a horizontal adjustment on a supporting-axle, a standard on which the axle is Vertically adjustable, and an attachingbracket for the standard having means for securing it at its ends respectively to the shoe and seedtube of the planter.

2. A furrow-opening attachment for planters and the like, comprising disks mounted to have a horizontal adjustment on a supporting-axle, a standard on which the axle is vertically adjustable, a pair of bracket-arms, means for adjustably securing said arms to the planter, blocks carried by the bracketarms and between which the standard is confined and means for clamping together the arms, blocks and standard.

3. A furrow-opening attachment for planters and the like,con1prising disks,a block carrying axles on which the disks are adjustably mounted, a standard square in cross-section and adjustable in an opening in the block, set-screws for maintaining the adjustment, and bracket-arms secured at their ends to the planter and supporting the upper end of the standard.

4. In a furrow opening attachment for planters and the like, a disk having a hub flanged at its inner end, an axle on which the disk is adjustable said axle having its outer end terminating short of the outer end of the hub to provide an oil-chamber, and means engaging the flange to maintain the adjusted position of the disk on the axle.

5. In -a furrow opening attachment for planters and the like, a disk having a flanged hub, an axle on which the disk is adjustable, a set-collar on the axle having an arm, a plate secured to said arm and engaging the hub-flange, and a scraper secured at its inner end to said arm.

In testimony whereof I affix my signature in presence of two witnesses.

- CLAUDE S. KEMPER.
